Hi all,
I just got handed a package deal of vehicles, one of which is a 1995 RamVan conversion with 5.2L and 3-spd O/D auto trans. It was from a friend who never really used it, and so I don't know much of the history other than the 169k mi on the clock.
It will not restart for 1-1.5 hours after being driven. It cranks but will not fire. A shot of starter fluid shows that there is spark, but apparently no fuel (very hard to hear the fuel pump prime, but I'm pretty sure I do not hear it when it is refusing to start). After researching on here and other forums the ASD and fuel pump relays sounded like a likely culprit. I replaced them and the problem persists.
Interestingly, if you shut it off and try to start it within a few minutes, it starts. It's only if you let it sit for 10+ minutes that it no longer wants to start. Something electric must be causing the fuel to not deliver (most likely the fuel pump not being told to cycle).
I have a '91 B250 with 5.2L but unfortunately the service manual I have does not cover the sequential-port injected versions of this van, just carb and TBI vans. I have more time than money currently, so when a manul arrives in the mail I will be trying to troubleshoot. If the ASD/ fuel pump relays are not the problem, what do you all think a logical order would be in checking? I'm hoping tomorrow to snag my neighbor to cylce the key so I can certify the relays are clicking (so hard to tell by just sticking my head out the window). From there I will likely need the manual to start ringing wires and checking things.
Oh, also, no check engine light. I don't have a reader and it does not do the key-cycle like my '91, so I assume it is OBD-II and needs a reader. The CEL does physically work (no one pulled the bulb or anything), but it has not come on to indicate a problem.
It's going to be a few days till I get the manual in the mail so I am trying to plan an order of operations to get as much tested in the 1-1.5 hours it is acting up after shutdown.
Thanks,
Johnny
